What are the characteristics of cartilage?
Definition: Cartilage is a tough, semitransparent, elastic, flexible connective tissue consisting of cartilage cells scattered through a glycoprotein material that is strengthened by collagen fibers.
What makes hyaline cartilage unique?
Hyaline cartilage is high in collagen, a protein that is found not only in connective tissue but also in skin and bones, and helps hold the body together. Hyaline cartilage provides support and flexibility to different parts of the body.Oct 4, 2019
What are the three characteristics of cartilage?
It consists of the following three elements: cells, fibers, and a ground substance (or extracellular matrix). hyaline cartilage: A type of cartilage found on many joint surfaces; it contains no nerves or blood vessels, and its structure is relatively simple.
How do you identify hyaline cartilage?
Hyaline cartilage. Cartilage is easy to recognize because it looks so much different from other tissues. This image shows a section of the wall of the trachea. You can feel the hyaline cartilage in your own trachea by pressing you fingers gently against the front of your throat and moving them slightly up and down.
What is the function of the hyaline cartilage?
Articular Cartilage Where bone ends meet to form a joint, they are covered by hyaline cartilage. This cartilage appears bluish white and glistening in a normal healthy joint. Its primary function is to provide some cushioning and minimize friction between the bone ends.
Which of the following best describes the characteristics of fibrocartilage?
characteristics. Fibrocartilage is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons; it is similar to other fibrous tissues but contains cartilage ground substance and chondrocytes.
How does hyaline cartilage differ from other cartilage?
Hyaline cartilage is easily distinguished from elastic and fibrocartilage because of the homogeneous (no fibers are visible) extracellular matrix (ECM) .
Why hyaline cartilage has glassy appearance?
Hyaline cartilage This type of cartilage has a glassy appearance when fresh, hence its name, as hyalos is greek for glassy. It looks slightly basophilic overall in H&E sections. Hyaline cartilage has widely dispersed fine collagen fibres (type II), which strengthen it. The collagen fibres are hard to see in sections.
Which is a characteristic of cartilage connective tissue?
Cartilage is a form of connective tissue in which the ground substance is abundant and of a firmly gelated consistency that endows this tissue with unusual rigidity and resistance to compression.
Where is hyaline cartilage found in the body?
Hyaline cartilage is the glass-like (hyaline) and translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs, nose, larynx, and trachea. Hyaline cartilage is pearl-grey in color, with a firm consistency and has a considerable amount of collagen.
What is hyaline cartilage?
The word hyaline means “glass-like”, and hyaline cartilage is a glossy, greyish-white tissue with a uniform appearance. It is one of the three types of cartilage; the other two types are elastic cartilage and fibrocartilage. Hyaline cartilage is the most abundant type of cartilage in the body.
What type of collagen is found in hyaline cartilage?
Hyaline cartilage contains type II collagen. All cartilage contains type II collagen; only fibrocartilage has both type I and type II collagen. Type I is found in organs, skin, tendons, and bones. Type III is a main component of reticular fibers in soft tissues like the liver, while type IV makes up the basal lamina.
Where is hyaluronic cartilage found?
It is found in structures like the nose, ears, and areas where the ends of the ribs attach to the sternum, and in parts of the respiratory system like the trachea and larynx, where it helps give these parts their form but also gives them some flexibility.
What is collagen found in?
Collagen – A protein that is found in skin and connective tissue; it is the most common protein in the human body. Fiber ( anatomy) – An elongated filament found in connective tissue. Perichondrium – A layer of connective tissue that surrounds hyaline cartilage and elastic cartilage; it has roles in growth, repair, ...
Where are chondrocytes found?
Chondrocytes are found in lac unae, which are small cavities that surround the chondrocytes. A primary lacuna is a lacuna containing one chondrocyte. When that cell divides, the daughter cells form new boundary layers called secondary lacunae, and the group of cells with lacunae is called a cell nest. Hyaline cartilage is very uniform in appearance.
Where is articular cartilage found?
Articular cartilage is hyaline cartilage that is found on the articular surfaces of bone, which is where bones meet and form joints. Hyaline cartilage is also found on the larynx, but there is no articular cartilage there since the larynx is not a bone. 2. Which is NOT one of the three types of cartilage?
Does cartilage have blood vessels?
Cartilage tissue does not have nerves or blood vessels. Instead, it has a simple structure that is mainly made up of groups of cells called chondrocytes embedded in an intracellular matrix. The protoplasm (inside content of the cell) is clear, and the cells have one or two nuclei.
Where is hyaline cartilage located?
In adults, hyaline cartilage is located in the articular surfaces of movable joints, in the walls of the respiratory tracts (nose, larynx, trachea, and bronchi ), in the costal cartilages, and in the epiphyseal plates of long bones.
What is the ECM of hyaline cartilage?
Matrix. The extracellular matrix (ECM) of hyaline cartilage is homogeneous and glassy, rich in in type II collagen, proteoglycans such as aggrecan, and structural glycoproteins such as chondronectin. Aggrecan is the most abundant proteoglycan in hyaline cartilage; hundreds of these aggrecans are bound noncovalently by link proteins ...
Why is cartilage important?
It is essential for the growth and maintenance of cartilage, as it harbors its vascular supply, as well as its nerves and lymphatic vessels. Although the articular cartilage of movable joints is not covered by perichondrium, they are sustained by diffusion of oxygen and nutrients from synovial fluid.
What is the layer of cartilage that surrounds all hyaline cartilage?
All cartilage is avascular and receives nutrients by diffusion from capillaries originating from the perichondrium. Perichondrium is a layer of dense connective tissue that surrounds all hyaline cartilage, except in the articular cartilage of movable joints. It is essential for the growth and maintenance of cartilage, as it harbors its vascular supply, as well as its nerves and lymphatic vessels. Although the articular cartilage of movable joints is not covered by perichondrium , they are sustained by diffusion of oxygen and nutrients from synovial fluid. The perichondrium consists mostly of fibroblasts, chondroblasts, and collagen type I fibers.
Why are chondrocytes important?
Chondrocytes are important in synthesizing and maintaining components of the ECM. At the periphery, young chondrocytes (or chondroblasts) have an elliptic shape, with their long axis parallel to the surface. At the core, mature chondrocytes have a round shape and often appear as a group of up to eight cells.
How many cells are in a chondrocyte?
At the core, mature chondrocytes have a round shape and often appear as a group of up to eight cells. These groups are known as isogenous aggregates, which originate from the mitotic divisions of a single chondrocyte.
